Okay, so my cells and BMS came. Now I’ve just got to wait for my spot welder to arrive before I start making my pack. Here’s my revised diagram:
Thoughts?
I’ve been reading about how much nickel strip I actually need, and it seems like 1 layer (of 3 individual strips that are 0.2mm x 10mm) seems to be enough for the parallel connections (since the current is shared across all 4 cells), and 2 12AWG wires should be enough for the serial connections (where a lot of current will travel between battery groups). Is my understanding correct/are these amounts of nickel and wire safe for a 10s4p S30Q pack?
